A Concept Study For Bottom-Up Part-Based Design

Inspired by nature, this paper presents an example of a bottom-up part based design approach. Design can be more similar to biological construction than engineering, focusing on parts and a series of actions generating a final result from these parts. Based on this principle, the paper introduces a generative method that uses a genetic algorithm (GA) from an earlier stage. It creates a part-based design paradigm informed by the initial given geometry, performance, function, and assembly logic. The part-based system is structured to include several 2D pieces to create 3D parts, and these parts to create a whole, an object. The paper utilises this system to generate a stool. The fitness function of the GA includes structural stability, top surface area, leg space, and part-to-part distance. The paper presents the structural calculations of the example stool model.
